    Everyone is permitted to copy and distribute verbatim copies of this license document,
    but changing it is not allowed.

    <p>
        Preamble</p>
    <p>
        The licenses for most software are designed to take away your freedom to share and
        change it. By contrast, the GNU General Public License is intended to guarantee
        your freedom to share and change free software--to make sure the software is free
        for all its users. This General Public License applies to most of the Free Software
        Foundation's software and to any other program whose authors commit to using it.
        (Some other Free Software Foundation software is covered by the GNU Library General
        Public License instead.) You can apply it to your programs, too.
        <br />
    </p>
    <p>
        When we speak of free software, we are referring to freedom, not price. Our General
        Public Licenses are designed to make sure that you have the freedom to distribute
        copies of free software (and charge for this service if you wish), that you receive
        source code or can get it if you want it, that you can change the software or use
        pieces of it in new free programs; and that you know you can do these things.
        <br />
    </p>
    <p>
        To protect your rights, we need to make restrictions that forbid anyone to deny
        you these rights or to ask you to surrender the rights. These restrictions translate
        to certain responsibilities for you if you distribute copies of the software, or
        if you modify it.
        <br />
        <br />
        For example, if you distribute copies of such a program, whether gratis or for a
        fee, you must give the recipients all the rights that you have. You must make sure
        that they, too, receive or can get the source code. And you must show them these
        terms so they know their rights.
        <br />
        <br />
        We protect your rights with two steps: (1) copyright the software, and (2) offer
        you this license which gives you legal permission to copy, distribute and/or modify
        the software.
        <br />
        <br />
        Also, for each author's protection and ours, we want to make certain that everyone
        understands that there is no warranty for this free software. If the software is
        modified by someone else and passed on, we want its recipients to know that what
        they have is not the original, so that any problems introduced by others will not
        reflect on the original authors' reputations.
        <br />
        <br />
        Finally, any free program is threatened constantly by software patents. We wish
        to avoid the danger that redistributors of a free program will individually obtain
        patent licenses, in effect making the program proprietary. To prevent this, we have
        made it clear that any patent must be licensed for everyone's free use or not licensed
        at all.
        <br />
        <br />
        The precise terms and conditions for copying, distribution and modification follow.
        <br />
    </p>
    <p>
        GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
        <br />
        <br />
        0. This License applies to any program or other work which contains a notice placed
        by the copyright holder saying it may be distributed under the terms of this General
        Public License. The "Program", below, refers to any such program or work, and a
        "work based on the Program" means either the Program or any derivative work under
        copyright law: that is to say, a work containing the Program or a portion of it,
        either verbatim or with modifications and/or translated into another language. (Hereinafter,
        translation is included without limitation in the term "modification".) Each licensee
        is addressed as "you".
        <br />
        <br />
        Activities other than copying, distribution and modification are not covered by
        this License; they are outside its scope. The act of running the Program is not
        restricted, and the output from the Program is covered only if its contents constitute
        a work based on the Program (independent of having been made by running the Program).
        Whether that is true depends on what the Program does.
        <br />
        <br />
        1. You may copy and distribute verbatim copies of the Program's source code as you
        receive it, in any medium, provided that you conspicuously and appropriately publish
        on each copy an appropriate copyright notice and disclaimer of warranty; keep intact
        all the notices that refer to this License and to the absence of any warranty; and
        give any other recipients of the Program a copy of this License along with the Program.
        <br />
        <br />
        You may charge a fee for the physical act of transferring a copy, and you may at
        your option offer warranty protection in exchange for a fee.
        <br />
        <br />
        2. You may modify your copy or copies of the Program or any portion of it, thus
        forming a work based on the Program, and copy and distribute such modifications
        or work under the terms of Section 1 above, provided that you also meet all of these
        conditions:
        <br />
        a) You must cause the modified files to carry prominent notices stating that you
        changed the files and the date of any change.
        <br />
        b) You must cause any work that you distribute or publish, that in whole or in part
        contains or is derived from the Program or any part thereof, to be licensed as a
        whole at no charge to all third parties under the terms of this License.
        <br />
        c) If the modified program normally reads commands interactively when run, you must
        cause it, when started running for such interactive use in the most ordinary way,
        to print or display an announcement including an appropriate copyright notice and
        a notice that there is no warranty (or else, saying that you provide a warranty)
        and that users may redistribute the program under these conditions, and telling
        the user how to view a copy of this License. (Exception: if the Program itself is
        interactive but does not normally print such an announcement, your work based on
        the Program is not required to print an announcement.)
        <br />
        <br />
        These requirements apply to the modified work as a whole. If identifiable sections
        of that work are not derived from the Program, and can be reasonably considered
        independent and separate works in themselves, then this License, and its terms,
        do not apply to those sections when you distribute them as separate works. But when
        you distribute the same sections as part of a whole which is a work based on the
        Program, the distribution of the whole must be on the terms of this License, whose
        permissions for other licensees extend to the entire whole, and thus to each and
        every part regardless of who wrote it.
        <br />
        <br />
        Thus, it is not the intent of this section to claim rights or contest your rights
        to work written entirely by you; rather, the intent is to exercise the right to
        control the distribution of derivative or collective works based on the Program.
        <br />
        <br />
        In addition, mere aggregation of another work not based on the Program with the
        Program (or with a work based on the Program) on a volume of a storage or distribution
        medium does not bring the other work under the scope of this License.
        <br />
        <br />
        3. You may copy and distribute the Program (or a work based on it, under Section
        2) in object code or executable form under the terms of Sections 1 and 2 above provided
        that you also do one of the following:
        <br />
        a) Accompany it with the complete corresponding machine-readable source code, which
        must be distributed under the terms of Sections 1 and 2 above on a medium customarily
        used for software interchange; or,
        <br />
        b) Accompany it with a written offer, valid for at least three years, to give any
        third party, for a charge no more than your cost of physically performing source
        distribution, a complete machine-readable copy of the corresponding source code,
        to be distributed under the terms of Sections 1 and 2 above on a medium customarily
        used for software interchange; or,
        <br />
        c) Accompany it with the information you received as to the offer to distribute
        corresponding source code. (This alternative is allowed only for noncommercial distribution
        and only if you received the program in object code or executable form with such
        an offer, in accord with Subsection b above.)
        <br />
        <br />
        The source code for a work means the preferred form of the work for making modifications
        to it. For an executable work, complete source code means all the source code for
        all modules it contains, plus any associated interface definition files, plus the
        scripts used to control compilation and installation of the executable. However,
        as a special exception, the source code distributed need not include anything that
        is normally distributed (in either source or binary form) with the major components
        (compiler, kernel, and so on) of the operating system on which the executable runs,
        unless that component itself accompanies the executable.
        <br />
        <br />
        If distribution of executable or object code is made by offering access to copy
        from a designated place, then offering equivalent access to copy the source code
        from the same place counts as distribution of the source code, even though third
        parties are not compelled to copy the source along with the object code.
        <br />
        <br />
        4. You may not copy, modify, sublicense, or distribute the Program except as expressly
        provided under this License. Any attempt otherwise to copy, modify, sublicense or
        distribute the Program is void, and will automatically terminate your rights under
        this License. However, parties who have received copies, or rights, from you under
        this License will not have their licenses terminated so long as such parties remain
        in full compliance.
        <br />
        <br />
        5. You are not required to accept this License, since you have not signed it. However,
        nothing else grants you permission to modify or distribute the Program or its derivative
        works. These actions are prohibited by law if you do not accept this License. Therefore,
        by modifying or distributing the Program (or any work based on the Program), you
        indicate your acceptance of this License to do so, and all its terms and conditions
        for copying, distributing or modifying the Program or works based on it.
        <br />
        <br />
        6. Each time you redistribute the Program (or any work based on the Program), the
        recipient automatically receives a license from the original licensor to copy, distribute
        or modify the Program subject to these terms and conditions. You may not impose
        any further restrictions on the recipients' exercise of the rights granted herein.
        You are not responsible for enforcing compliance by third parties to this License.
        <br />
        <br />
        7. If, as a consequence of a court judgment or allegation of patent infringement
        or for any other reason (not limited to patent issues), conditions are imposed on
        you (whether by court order, agreement or otherwise) that contradict the conditions
        of this License, they do not excuse you from the conditions of this License. If
        you cannot distribute so as to satisfy simultaneously your obligations under this
        License and any other pertinent obligations, then as a consequence you may not distribute
        the Program at all. For example, if a patent license would not permit royalty-free
        redistribution of the Program by all those who receive copies directly or indirectly
        through you, then the only way you could satisfy both it and this License would
        be to refrain entirely from distribution of the Program.
        <br />
        <br />
        If any portion of this section is held invalid or unenforceable under any particular
        circumstance, the balance of the section is intended to apply and the section as
        a whole is intended to apply in other circumstances.
        <br />
        <br />
        It is not the purpose of this section to induce you to infringe any patents or other
        property right claims or to contest validity of any such claims; this section has
        the sole purpose of protecting the integrity of the free software distribution system,
        which is implemented by public license practices. Many people have made generous
        contributions to the wide range of software distributed through that system in reliance
        on consistent application of that system; it is up to the author/donor to decide
        if he or she is willing to distribute software through any other system and a licensee
        cannot impose that choice.
        <br />
        <br />
        This section is intended to make thoroughly clear what is believed to be a consequence
        of the rest of this License.
        <br />
        <br />
        8. If the distribution and/or use of the Program is restricted in certain countries
        either by patents or by copyrighted interfaces, the original copyright holder who
        places the Program under this License may add an explicit geographical distribution
        limitation excluding those countries, so that distribution is permitted only in
        or among countries not thus excluded. In such case, this License incorporates the
        limitation as if written in the body of this License.
        <br />
        <br />
        9. The Free Software Foundation may publish revised and/or new versions of the General
        Public License from time to time. Such new versions will be similar in spirit to
        the present version, but may differ in detail to address new problems or concerns.
        <br />
        <br />
        Each version is given a distinguishing version number. If the Program specifies
        a version number of this License which applies to it and "any later version", you
        have the option of following the terms and conditions either of that version or
        of any later version published by the Free Software Foundation. If the Program does
        not specify a version number of this License, you may choose any version ever published
        by the Free Software Foundation.
        <br />
        <br />
        10. If you wish to incorporate parts of the Program into other free programs whose
        distribution conditions are different, write to the author to ask for permission.
        For software which is copyrighted by the Free Software Foundation, write to the
        Free Software Foundation; we sometimes make exceptions for this. Our decision will
        be guided by the two goals of preserving the free status of all derivatives of our
        free software and of promoting the sharing and reuse of software generally.
        <br />
        <br />
        NO WARRANTY
        <br />
        <br />
        11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE
        PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED
        IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS"
        WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED
        TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
        THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD
        THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR
        OR CORRECTION.
        <br />
        <br />
        12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY
        COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM
        AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
        INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
        PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE
        OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE
        WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF
        THE POSSIBILITY OF SUCH DAMAGES.
        <br />
        <br />
        END OF TERMS AND CONDITIONS
        <br />
        <br />
        How to Apply These Terms to Your New Programs
        <br />
        <br />
        If you develop a new program, and you want it to be of the greatest possible use
        to the public, the best way to achieve this is to make it free software which everyone
        can redistribute and change under these terms.
        <br />
        <br />
        To do so, attach the following notices to the program. It is safest to attach them
        to the start of each source file to most effectively convey the exclusion of warranty;
        and each file should have at least the "copyright" line and a pointer to where the
        full notice is found.&nbsp;<br />
        <br /></p>
       <blockquote><p>
        &lt;one line to give the program's name and a brief idea of what it does.&gt;<br/>

        This program is free software; you can redistribute it and/or modify it under the
        terms of the GNU General Public License as published by the Free Software Foundation;
        either version 2 of the License, or (at your option) any later version.
    </p>
   <p> 
        This program
        is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without
        even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
        See the GNU General Public License for more details. 
    </p>
   <p>
        You should have received a
        copy of the GNU General Public License along with this program; if not, write to
        the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307
        USA </p>
    </blockquote>
    <p>
        Also add information on how to contact you by electronic and paper mail. 
    </p>
    <p>
        If
        the program is interactive, make it output a short notice like this when it starts
        in an interactive mode: 
    </p>
    <blockquote>
        Gnomovision version 69, Copyright (C) year name of author
        <br />
        Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.<br />
        This is
        free software, and you are welcome to redistribute it under certain conditions;
        type `show c' for details. 
    </blockquote>
    <p>
        The hypothetical commands `show w' and `show c' should
        show the appropriate parts of the General Public License. Of course, the commands
        you use may be called something other than `show w' and `show c'; they could even
        be mouse-clicks or menu items
        -whatever suits your program. 
    </p>
    <p>
        You should also get
        your employer (if you work as a programmer) or your school, if any, to sign a "copyright
        disclaimer" for the program, if necessary. Here is a sample; alter the names: 
    </p>
    
<blockquote>    
    <p>
        Yoyodyne,
        Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which
        makes passes at compilers) written by James Hacker.</p>

    <p>
        This General Public License does not permit
        incorporating your program into proprietary programs. If your program is a subroutine
        library, you may consider it more useful to permit linking proprietary applications
        with the library. If this is what you want to do, use the GNU Library General Public
        License instead of this License.
